Busy microbial world discovered in deepest ocean crust ever explored (November 19, 2010) -- The first study to ever explore biological activity in the deepest layer of ocean crust has found bacteria with a remarkable range of capabilities, including eating hydrocarbons and natural gas, and "fixing" or storing carbon. ... > full story
Pomegranate juice reduces damage to tissues, inflammation and infections, study suggests (November 19, 2010) -- Studies in recent years have claimed multiple health benefits of pomegranate juice, including that it is a good source of antioxidants and lowers both cholesterol and blood pressure, especially in diabetic and hypertensive patients. A preliminary study now suggests that it can ward off a number of complications in kidney disease patients on dialysis, according to new study. ... > full story
E. coli infection linked to long-term health problems (November 19, 2010) -- People who contract gastroenteritis from drinking water contaminated with E coli are at an increased risk of developing high blood pressure, kidney problems and heart disease in later life, finds a new study. ... > full story
New disease-resistant food crops under development (November 19, 2010) -- Researchers have uncovered the genetic basis of remarkable broad-spectrum resistance to a viral infection that, in some parts of the world, is the most important pathogen affecting leafy and arable brassica crops including broccoli, cauliflower, cabbage, kale, swede and oilseed rape. They have tested resistant plants against a range of different strains of the virus taken from all over the world and so far, no strain has been able to overcome the resistance. ... > full story
Paw prints and feces offer new hope for saving tigers (November 19, 2010) -- How many tigers are left in the wild can now be monitored accurately from their paw prints and scat (feces), ecologists have shown for the first time. The new technique at last gives conservationists a low-cost and reliable way of assessing tiger numbers, information that is crucial to saving the species from extinction in the wild. ... > full story
Chemicals' study pinpoints threat to workers' lungs (November 19, 2010) -- Tiny particles used in a range of everyday products from computers to shampoo can adversely affect the lungs in very different ways, a study has shown. Research suggests that industrial manufacturers using nanoparticles should be aware of the risks that different types of nanoparticles pose to workers who handle them. ... > full story
Doomsday messages about global warming can backfire, study shows (November 19, 2010) -- Dire or emotionally charged warnings about the consequences of global warming can backfire if presented too negatively, making people less amenable to reducing their carbon footprint, according to new research. ... > full story
Ten years of Soufriere Hills Volcano research (November 19, 2010) -- The Soufriere Hills Volcano on Montserrat erupted in 1995, and researchers have studied this volcano from land and sea since then to understand the workings of andesite volcanoes more completely. ... > full story
FDA review on transgenic salmon too narrow, experts say (November 19, 2010) -- The review process being used by the Food and Drug Administration to assess the safety of a faster-growing transgenic salmon fails to weigh the full effects of the fish's widespread production, according to new analysis. ... > full story
Bees take the sting out of mouth ulcers (November 19, 2010) -- The healing properties of propolis -- a mixture of resin and wax made by honey bees to seal and sterilize their hives -- have been known for many years. But its use in medicine and food supplements has been limited because the sticky substance is not water soluble and has a strong, off-putting smell. Now researchers have developed a way of purifying propolis that retains its medicinal properties, but makes it dissolve in water and eliminates its pungent smell. ... > full story
Panama Canal, Panama City at risk of large earthquake, says new research (November 19, 2010) -- New data suggest that the Limon and Pedro Miguel faults in Central Panama have ruptured both independently and in unison over the past 1400 years, indicating a significant seismic risk for Panama City and the Panama Canal. ... > full story
Why so many antibodies fail to protect against HIV infection (November 19, 2010) -- Researchers have been stymied for years over the fact that people infected with the AIDS virus do indeed produce antibodies in response to the pathogen -- antibodies that turn out to be ineffective in blocking infection. Now, scientists can explain why: Some of the earliest and most abundant antibodies available to fight HIV can't actually "see" the virus until after it's already invaded a healthy cell. ... > full story
